It turns out a zombie mythbackend process is creating my problems, and the
backend is not restarting like I assumed before. Please follow my bug
report, I have a ton of GDB/Strace captures there...
My backend not accepting connections still remains, and it is somehow tied
in with the "waiting for a thread.." error messages.
